Abstract

L'invention concerne un procédé destiné à la détection d'un constituant en phase gazeuse, tel que du monoxyde de carbone, du dioxyde d'azote, de l'hydrogène ou des hydrocarbures, dans un gaz comprenant de l'oxygène, tel que l'air, consistant à utiliser une substance ou une pellicule sensible (20, 120) constituée d'un métal noyé dans une matrice catalytiquement active, tel que de l'or noyé dans une matrice d'oxyde de zirconium stabilisé à l'yttrium (YSZ). Le procédé peut consister à soumettre la substance sensible à un recuit à une température de 900°C environ, à exposer la substance sensible (20, 120) et le gaz à une température supérieure à 400°C, à projeter de la lumière sur la substance sensible (20, 120) et à détecter une variation dans le spectre d'absorption de la substance sensible due à l'exposition de la substance sensible au gaz dans l'air à la température qui produit une réaction chimique dans la substance sensible par rapport au spectre d'absorption de la substance sensible en l'absence du gaz. L'invention concerne également des systèmes (700) dans lesquels ce procédé est mis en oeuvre.
